Metal-insulator transitions and nanoscale phase separation in various underdoped cuprates

Blog Article

We demonstrate that the unconventional electron-phonon Vehicles interactions, charge inhomogeneity and charge ordering in underdoped cuprates play an important role in metal-insulator transitions and nanoscale phase separation.In so doing, we argue that charge carriers (i.e.hole polarons) in these systems segregate into insulating (copyright-poor) and metallic/superconducting (copyright-rich) regions as a result of their specific ordering.We show that the metal-insulator transitions, nanoscale phase separation and coexisting insulating and metallic/superconducting phases are manifested in the unusual temperature dependences of the magnetic susceptibility and resistivity and in Food and Beverage the suppression of superconductivity in various underdoped cuprates.
